Error in Edge server mail queue LED=451 4.7.0 Temporary server error. Please try again later. PRX6
We have two Edge servers deployed at our Central location where it accepts mails from all other site and send it to Internet and vice versa. There is no problem for outgoing mails but while receiving the mails from the internet there is always an average
queue of 600 to 700 mails (some time goes up to 2000). After analysing the issue we found the below errors..
LED=451 4.7.0 Temporary server error. Please try again later. PRX6
451 4.4.0 SMTPSEND.SuspiciousRemoteServerError; remote server disconnected abruptly; retry will be delayed
421 4.4.2 Connection dropped due to TimedOut
We have then picked random 10/12 recipients from the error queue and found all of ‘em were
from a specific site.
we have tried the below solution... after searching for resolution on the Internet
Tried enabling protocol logging but nothing found
Since it was more likely to be a DNS issue, tried manually adding DNS server IPs in the ‘Default front end receive connector’ properties.
Tried adding DNS server IPs manually into both Transport servers in ‘DNS Lookup’ setting in the server properties.
Tried adding local server's IP to the hosts file.
Checked if SMTP fixup is enabled on Firewall.
Verified the receive connector security settings.
Verified the CPU and Memory utilization is normal.
Disabled the Performance Counter on both Transport Server to ensure memory usage.
but nothing seems helping
now the problem is because of this there is a mail delay of at least 20 minutes for incoming mails.
Need help resolving the same.

I think its working now ..
after researching a lot on events on Transport servers we got to know that 'Default Frontend Receive Connector' was rejecting some messages...
we have then increased the value for the parameter "MaxInboundConnectionPerSource" from 20 to unlimited and
MaxInboundConnectionPercentagePerSource
from 2 to 10.. we have the waited for 2 to three hours .. the queue then came down from 1500 to 5 and petty stable thereafter.
we will be monitoring the same for few days from now.

I don't recall this happening before.
Is it an issue with Mozilla Thunderbird or with Telecom New Zealand ?I am now receiving emails..........
To answer your questions, probably because I'm ignorant, illiterate, old and useless.
In future I will contact my provider first.
Greatly appreciate your help. -
Please give me a solution asap.

MSDN Internet Server error: Sorry, we were unable to service your request. Please try again later.
I have been experiencing a high rate (maybe 1 in 5 page renders) errors from the MSDN servers in the last 4-6 weeks.
It reports in the breadcrumb "Internal Server error"
And then writes below: Sorry, we were unable to service your request. Please try again later.
Is Microsoft aware of this ongoing and high rate issues?
--DaleThere are many who are facing this issue.

Hi all,
I have just deployed Exchange 2013 on two CAS boxes and two MBX boxes as follows:

Can anyone help? I'm at the end of my Googling!The answer has been found. In our case, we had to disable the Mailguard feature of the Cisco ASA between the CAS subnet and the MBX subnet. Essentially it was stripping AUTH commands from the SMTP handshake which meant the servers could not authenticate
to each other and establish a secured connection.
I guess for future reference, if you're getting a PRX4 error code you should look at any device that could be inspecting SMTP between your CAS and MBX servers.

Exchange 2013 "451 4.7.0 Temporary server error. Please try again later. PRX5" Error
I know this error message is discussed on other topics on several different forums including TechNet but I ended up opening this as the suggestions that solved the problems with the previous threads dos not work on mine.
We have a ticketing software that runs on client computers which sends mails to local Exchange server for notifications using port 25.
Approximately 1 out of 5 mails end up getting the "451 4.7.0 Temporary server error. Please try again later. PRX5" error. I have confirmed this by running Wireshark on the clients, saw the exact error message. This has been replicated with
several client machines running Win7 & 8.
I have tried several solutions to this, one of them being this:
http://www.techieshelp.com/exchange-2013-451-4-7-0-temporary-server-error-please-try-again-later-prx5/
I still get the same error from time to time after doing this, so it is not the issue. All the records in local hosts file, receive connector is listening to port 25 on all IPv4 addresses.
The server has a single NIC and the DNS lookups are done through that single NIC, not through "All available adapters" as set by default on ECP.
Almost everyone seems to be convinced that this is related to DNS but looking at how fast I get the error message, it doesn't look like it's waiting for a timeout (maybe unrelated, just an observation). Do you think it is possible that the DNS servers themselves
are causing this issue?
Also, I see Event 5504 on the primary dns server almost all of them coming from the mail server, saying that the DNS query was invalid. It may be related.
Additional Notes:
- CU6 is applied but did not fix the issue.
- None of these have solved it for me: http://www.servolutions.com/support/articles/Temporaryservererror2013.htm
- Receive Connectors do listen to separate ports 25 & 2525 -> There is a single instance of both Transport Service and Edge Transport service respectively. Anonymous users are accepted in both Receive connectors.Thank you for your post.
This is a quick note to let you know that we are performing research on this issue.

451 4.7.0 temporary server error. please try again later. prx4
Hello,
in my environment i can send/receive mail.
When doing some checks i will end up with this error :
451 4.7.0 temporary server error. please try again later. prx4
I have tried the following without results :
Exchange 2013 SMTP error "451 4.7.0 Temporary server error. Please try again later. PRX3"
This error message seems to be caused by DNS issues in the Exchange 2013 set up. Exchange then rejects all emails like this. It is not quite clear what Microsoft means with this error code and the various PRX-numbers at the end - we've also seen PRX1, PRX3,
PRX7. There is no list and no documentation on them available.
From customer feedback we found these ways to solve the problem:
Disable all unused network cards.
Check all DNS server entries in the configuration of your network cards (check
all network adapters) and make sure not to reference server 127.0.0.1 as DNS server but to use the real IP address instead.
If you have more than one fixed IP address in the server add an entry for each IP address in the hosts file (C:\Windows\System32\drivers\etc\hosts) formatted like "192.168.1.1 SERVERNAME".
Important: Do load the latest Exchange 2013 updates, especially CU1 if you haven't done that already.
Please delete the receive connectors in Exchange and create one new receive connector. Use the "front end" instead of "hub transport" setting and vice versa.
What do do, to fix this issue?
ThxHello,
Please use dcdiag command to check if all DC run normally.
Please use repadmin /showrepl command to verify DC replication status.
Please check if there is any related error in application log.

I've signed up for Office 365 Business Essentials service, and I have trouble sending and receiving emails. All the messages I send to my email associated with this account get a reply with error message
451 4.7.0 Temporary server error. Please try again later. PRX2
Additionally, all the mails I send from Outlook OWA in a browser and with iPhone app are stuck in Drafts folder and are not sent anywhere.
This is what I tried:
Checked the mail flow in Exchange admin center. There are no mail rules, no inbound or outbound connectors
Checked for DNS issues with my domain by clicking "Manage domains" in Admin center. Message was "barsukov.net domain is set up correctly. No action is
required."
Checked the MX records of my domain, barsukov.net, which point to a correct domain suggested by Microsoft.
Most of the search results related to this error suggest to add entries to hosts file on server with Exchange. This is not applicable to my case, obviously, since I use a cloud version of Exchange.
How to fix this issue?It takes some time for newly added domains to be recognized by the service. If the issue persists, open a case with MS support:

451 4.7.0 Temporary server error. Please try again later. PRX5
I've noticed that on occassion when I connect to my Exchange 2013 CU 1 server, the server will respond with "451 4.7.0 Temporary server error. Please try again later. PRX5" after I submit an e-mail for delivery. It accepts the sender, verifies
the recipient, asks for data and fails only upon submission. Trying again right after the failure usually takes care of the problem what that's not a fix. What's causing the problem? Anyone else seen this?whohoo, i FINALLY figured it out - and what can i say? the cause was another hickup of the ECP, i would call it a bug but what do i know? ;)
turns out that ex2013 has huge problems when you leave the DNS lookups setting in the server properties to "All network adapters", instead you should select a specific NIC or enter the IPs of your DNS servers manually. well, this is mentioned in numerous threads
all over the forums and obviously for many people, that was the solution.
BUT...i still had no mail flow after setting the DNS servers manually and my logs still filled up with DNS errors. in the end it turned out that the setting in the ECP only configures the transport service, but NOT the the frontend transport service. you can
easily check this with get-transportservice and get-frontendtransportservice and looking at the ExternalDNS and InternalDNS settings...sure enough, for me only the Transport Service had the configuration applied that i set in the ECP.
so, i configured set-frontendtransportservice with the same DNS settings as the transport service, and finally my mailflow is working...i can hardly believe it, and i can't believe that i found literally nothing about this behavior/bug of the ECP on the net.
so, this is my solution - maybe it helps someone else :) -
451 4.7.0 Temporary server error. Please try again later. PRX2
I'm getting the dreaded "
451 4.7.0 Temporary server error. Please try again later. PRX2
" error when receiving SMTP mail.
does anyone know exactly what causes this error? there are many references to it on the web, but nobody seems to know exactly what causes it. maybe it's something to do with DNS?
can someone please ask someone on the exchange team to help document this?Option A works for me...
Important: DNS Lookup issues
may prevent or delay message delivery or cause items to sit in OWA Drafts folder (7/22)
I’ve been following a thread on this since CU1\April but just now getting around to post it here, sorry for the delay if you’ve hit this issue
Tony Redmond’s also covered this on his blog here:http://thoughtsofanidlemind.wordpress.com/2013/03/25/exchange-2013-dns-stuck-messages/
In some environment message delivery will fail with the following error or be delayed by many seconds or minutes.
451 4.7.0 Temporary server error. Please try again later. PRX5
Threads on MS TechNet Forums: http://bit.ly/14A1JQY &http://bit.ly/13UG1ks
Quick Fix:
Option A: Set the NIC to use for “External DNS lookups” in EAC under Servers
Option B: Set ExternalDNSAdapterEnabled and InternalDNSAdapterEnabled to $false and set DNS servers on ExternalDNSServers and InternalDNSServers with the Set-FrontendTransportService command
Others have used a host file with the Exchange 2013 servers in it, but the above method is easier to manage -
I have icloud and a new iPhone5 ! They work good , took pictures and a few short movies, plugged in my phone to my iMac transfered Items to iPhoto then inported items to iMovie. when getting to know what i was doing i decided to delete pictures and movies i no longer wanted. when i looked for a few missing items i opend Finder and there some where buyt i had already trashed them and deleted the doubles. Still could not find missing pictures and movies 3 items and today after calling yahoo about a different complant with sending feed back for Yahoo mail Applications login . i opened up Attachments Not the Large Attachments just Attachments and there were the 3 items i had been hunting for to Trash and delete. the mail Attachments file does not have the Option to delet Files and photos and movies. When i tried to Download the 3 items a window shows up that says Error While Downloading the Files, A Server Error has occured, please Try Again later. nothing works how do i remove the Trapped photo and movie Blank Files and trash them? Onece they get into my downloads i can do something with them as i understand. That part of it kind of keeps me in Question also because why should i have to down load my own files of Attachments / Pictures and movies if they are comming from my iMac? How much better is iLife11 then iPhoto08 and iMovie08 . Thanks Greg

Thanks. Regards.Hi,
If the CAS and MBX servers are collocated on the same server the SMTP Receive connection for the Transport service will listen on 2525 instead of 25. This is because two services (FET and Transport Service) can’t listen on the same port.
Refer from this article:
http://blogs.technet.com/b/rischwen/archive/2013/03/13/exchange-2013-mail-flow-demystified-hopefully.aspx
Please try to create an endpoint for 2525 on default receive connector to test mail flow by the following steps:
EAC -> mail flow -> receive connectors -> Default EXCHANGE
Click Edit then click scoping tab.
Under Network adapter bindings, click
add button to create port 2525 for all available Ipv4/Ipv6 addresses.
Best Regards. -
